This tech pack was inspired by Tech World 2 which was made for Minecraft 1.6.4 and I really enjoyed playing that. I wanted to try the newer minecraft versions but couldn't find a good tech focused modpack which didn't also add a bunch of magic or make survival too easy. You will still need to start by crafting a pickaxe and gathering resources while later in the game your time may be spent managing your item storage drives and planning railroad lines. It works well for single player and can also be hosted as a server. The different mods integrate fairly well with each other, you can power your AE2 setup with a steam engine from Create or power your Create machines with a heat generator from Mekanism for example.
